Representation of urban geometry evolution through space-time cube

Résumé

Visualizing and understanding the evolution of neighbourhoods in cities is crucial to the understanding of urban areas. While data exists to document the evolution of the urban places, we lack methods to clearly visualize the evolution of a city or a neighbourhood in time. We propose a new representation of the city that integrates 3D urban data with time, inspired by the Space-Time Cube concept. Our representation allows the visualization and comparison of different versions of the city in a single interactive 3D space, based on a graph model of the data. In addition to displaying the 3D geometry, we also integrate a direct visualization of the type of changes between each version and provide several ways to interact with the visualization. We apply our visualization technique on real urban data and show that it allows quickly apprehending the evolution of a neighbourhood.
